The invention discloses a distributing device provided with an interlocking hydraulic control system. The distributing device comprises a cabinet, a backing ring which is arranged in the cabinet and capable of sliding up and down along the inner wall of the cabinet, three or more oil cylinders which are arranged on the periphery of the backing ring and used for pulling the backing ring to slide upand down, and the hydraulic control system used for controlling the three or more oil cylinders. The hydraulic control system comprises oil inlet paths connected with oil inlets of the three or moreoil cylinders correspondingly, and oil return paths connected with oil return ports of the three or more oil cylinders correspondingly. Hydraulic lock devices are arranged on the oil inlet paths and the oil return paths corresponding to the oil cylinders correspondingly. According to the technical scheme, by arranging the hydraulic lock devices on the oil inlet paths and the oil outlet paths of the oil cylinders arranged on the periphery of the backing ring, the phenomenon of oil intermingling among the oil cylinders can be avoided, it is guaranteed that the backing ring can still be kept horizontal and does not tip over when a distributing device chute makes movement by a beta angle, accordingly, scraping abrasion between the backing ring and the inner wall of the cabinet of the distributing device is avoided, and the service lives of key components such as the backing ring of the distributing device are prolonged.
